step 1 -> Create a flutter app

step 2 -> create views folder inside -> lib folder after that -> go inside views folder and create a stateful widget like ->
	home_screen.dart (it must be stateful widget) -> because we need initState() method to work with PushNotification 

step 3 -> Render home_screen.dart from main.dart as first screen from home: (Named Argument)
		
Now all setup is done to work with Pushnotification 

step 4 -> add these 3 Dependencies in pubspec.yaml
